SECTION 3 EQUIPMENT OPERATION AND MAINTENANCE
2/1 LOCATION
1.
Locate pump as close to the pool as practical.
Consult local codes for minimum distance between
pool and pump.
2.
The piping should be as direct and free from turns or
bends as possible, as elbows and other fittings greatly
increase friction losses.
3.
Place pump on a solid foundation which provides a
rigid and vibration-free support so that it is readily
accessible for service and maintenance.
4.
Protect the pump against flooding and excess
moisture, and prevent foreign objects from clogging
air circulation around motor.
5.
DO NOT store or use gasoline or other flammable
vapors or liquids in the vicinity of this pump. DO NOT
store pool chemicals near the pump.
6.
DO NOT remove any safety alert labels such as
DANGER, WARNING, or CAUTION. Keep safety
labels in good condition and replace missing or
damaged labels.
2/2 INSTALLATION
1.
When connecting pipework to pump it is recommended
that a flanged connection be used in the discharge line
directly above the pump (see figure 1). If the suction
pipe is not sealed correctly, the pump will not prime
properly and will pump small volumes of water or none
at all.
SECTION 4 MAINTENANCE
The pump requires little or no service other than
reasonable care and periodic cleaning of the strainer
basket. The seal on the pump is a mechanical seal.
The seal may come loose during the course of time,
depending on the running time and water quality. If
water continually leaks out, a new mechanical seal
should be fitted.
To replace a mechanical seal, remove the four nuts
holding the seal housing to the casing. Slide the motor
part including the seal-housing out. Remove impeller

BONDING: As required by National Electrical Code
Article 680-22, the pump motor must be electrically
bonded to the pool structure (reinforced bars, etc.) by
a solid copper conductor not smaller than #8 AWG via
the external copper bonding lug on the pump motor.

GROUNDING:
motor using a conductor of appropriate size. Connect
to the #10 green headed ground screw provided
inside the motor terminal box.
NOTE: Do not connect to electric power supply until
unit is permanently grounded.
When installing the pump, care should be taken to see
the suction line is below water level to a point immedi-
ately beneath the pump to ensure quick priming via a
flooded suction line. The height between the pump and
water level should not be more than 15 feet. Should it
not be possible to lay the pipework giving a flooded
suction, then a check valve should be fitted in the verti-
cal section of the suction line. The check valve will
ensure that the water in the pump starts priming. (Does
not apply to flooded suction application.)
Suction and discharge line should be independently
supported at a point near the pump to avoid strains
being placed on the pump.
It is advisable to install a gate valve in both the suction
and discharge line in the event that the pump must be
removed for servicing. (Flooded suction application
only)
Before starting the pump for the first time, remove the
lid. Fill pump body with water until level with suction
inlet. Replace lid, hand tight, making sure that the o-ring
is not damaged.
When installing and using the motor, basic safety
precautions should always be followed. The wiring of
motor should be done by a licensed electrician in accor-
dance with local codes. Be certain that the motor frame
is grounded. Motor name plate has voltage, phase,
ampere draw and other motor information as well as
wiring connection instructions.
Permanently ground the pump
nut by turning it counter-clockwise when facing it,
while holding motor shaft with a 1/2" wrench at rear
end of motor. Pull pump impeller from shaft and slide
seal from impeller shaft. To re-assemble, reverse the
process. (Use a drop of loctite to secure the impeller
nut.) Note: Make sure both parts of the mechanical
seal (ceramic and spring portion) are clean. Gently
wipe polished faces with soft and dry cotton cloth.
Surfaces can easily be damaged by dirt and scratching.
Only water should be used as lubricant to mount both
parts of the mechanical seal.
